Application filed April 3, 1909. Serial No. 487,728.

I '0 all whom it may concern:

Be tknown that I, \VILLIAM L. GUM- Pnnon'r, a citizen of the United States, residthe accompanying ing in the borough of registering Manhattan, of the city of New York, in the State of. New York, have invented certain new and useful Improvements in Meters, of which the followlng 1s a specification, reference being had to drawlng, forming a part hereof.

This invention relates to meters of the oscillating or nutating disk type in which the mechanism is actuated by a disk which oscillates or nutates in a disk chamber under the influence of the flow through such chamber of the liquid to be measured. In the operation of such meters it sometimes happens that a hard body of some kind, such as a small pebble, passes into the disk chamber and, lying between the face of the disk and the co ical wall of thechamber into close contict wit-h whichthe disk should come in its movements, prevents the proper movement of the disk.

7 such driving spindle.

The movement of arted to the registering mechthe disk is im a diskspindle which cooperanism throng gates with an arm on the driving spindle of v the registering mechanism and 1s guided in ll'S movement by contact with the head of I no provision for yielding between the disk I spin e and the driving spindle, theresult of such interference with the proper movement of the disk as above referred to is a breakage of some of the the disk.

]t is the object of this invention to reduce the danger of breakage from this cause and to that end a ielding cushion is inter used between the dlsk and the driving spin l of the registering mechanism which will perparts, usually a fracture of unit the disk to accommodate itself to a small hard body whi ch may be interposed between it and the adjacent conical face of the disk chamber until such body is washed out.

The invention will be more fully explained hereinafter with reference tothe accompanying drawlng in which different embodiments thereof are illustrated and in whichthe figure is a view, partly in section and partly in elevation, of so much of a nutatlng disk meter as is necessary to enable the invention to be understood.

The disk casing comprising the upper part and the lower part b, is provided with the I usual diaphragm 0 andinlet and outlet ports There being usually mounted above the arms [U spindle a conical head against which the upper end of the spindle z rests in its move-- and with a suitable seat f for the disk ball 9 which carries the nutating disk it. The

disk spindle-z projects through the upper disk casing a and cooperates with an arm is on the lower end of the driving spindle m of the register mechanism. In the ordinary construction of meters of this type there is of the driving merits, being guided thereby. Both the spindle and the guiding head are usually rigid so that there is no possibility of yielding, except in the disk itself, when a hard body enters the disk casing and rests between the disk and the conical surface of the disk chamber. A

In the embodiment of the present invention, which is illustrated in the'figure of the drawing, however, the conical guide head a is not rigid but is mounted movably the flared lower end of a sleeve 0 which is secured upon the bearing sleeve 72 of the spindle m. The lower end of the'sleeve 0 forms an annular, preferably spherical seat 0 upon which rests the suitably shaped an nular guiding headn, a spring r being interposed between the lower late 9 of the gear train and the upper end o the annular guiding head 1 to hold the'latter yicldingly upon its seat. It Will now be seen that if a hard body is interposed between the lower conical surface of the disk chamber and the disk, so as to prevent the disk from moving down into full. contact with the conical surface at that point, the yielding cushion afforded between thedisk spindle and the driving spindle by the-yielding guiding head a will permit the disk s indie to yield to the abnormal movement of the disk, the guiding head a being crowded up and to one side u on its seat 0 and returning to its l position as soon as the hard body has passed onthrough the disk chamber. It will be understood, of course, that the an nular guiding head'n' is conical interiorly, as well as exteriorly, so as to permit of its displacement upon its supporting sleeve 0 under abnormal condition.

I claim as my invention:

1. In an oscillating or mutating disk meter, the combination with the disk casing, disk, disk spindle and register-driving s indle provided with an arm to be engaged by the dish spindle, of an annular guiding head for cooperation with the disk spindle, an annularspherical seatupon which said guiding head is-.1n0vably supported and a spring its seat. 2; In an oscillating or nutating disk nieter, the combination of the register driving spindle provided with an-arm adapted to be engaged by the disk spindle, an annular guiding head for cooperation with the dish spindle, :1 seat upon which the guiding head is movably supported and. a spring holding the uide yi'eldingly uponits seat. holding the guide yieldingly upon T is specificatmn signed and witnessed this 1 day of April, A. D., 1909.
